I suppose you’re referring to the Neutron Music Player app?

I never heard of it and though it was a hardware player competing with the Walkman, but it’s another android music player from the look of it. I still checked the app page in case they went for completely different playing controls to compensate for the physical buttons and playing widget, but it seems it mainly focuses on EQ tweaking and “high fidelity” playback.

I’m all for alternative players on the market, so more power to them. But I’m probably not their target audience.
